Walnut Seed Oil Health Facts
Walnut oil is used not only in medicine. Thanks to its sophisticated and smooth taste, it is an essential component of Greek, French and Caucasian cuisine. Walnut oil contains about 75% of omega -3 and omega -6 polyunsaturated fatty acids. Therefore, these acids should be consumed in moderation. In addition, walnut oil is the biggest source of vitamin F. Vitamin F may be able to normalize blood pressure, thus reducing the risks of heart attacks. But the main function of vitamin F is cholesterol excretion.
One way nuts may help your heart health is by lowering the low-density lipoprotein (LDL, or “bad”) cholesterol levels. LDL plays a major role in the development of plaque that builds up on the blood vessels.
Unsaturated fats: It’s not entirely clear why, but it’s thought that the “good” fats in nuts — both monounsaturated and polyunsaturated fats — lower bad cholesterol levels.
Omega-3 fatty acids: Omega-3 are a healthy form of fatty acids that seem to help your heart by, among other things, preventing dangerous heart rhythms that can lead to heart attacks.
Fiber: All nuts contain fiber, which helps lower your cholesterol. Fiber makes you feel full, so you eat less. Fiber is also thought to play a role in preventing type 2 diabetes.
Vitamin E: Vitamin E may help stop the development of plaques in your arteries, which can narrow them. Plaque development in your arteries can lead to chest pain, coronary artery disease or a heart attack.
L-arginine. Nuts are also a source of l-arginine, which is a substance that may help improve the health of your artery walls by making them more flexible and less prone to blood clots that can block blood flow.
Walnut oil is a very useful dietary product that is easy to digest. It is considered to be an excellent source of energy and vitamins. Therefore, it is not surprising that walnut oil is included into various diets. Walnut oil is good for face and body skin, hair and nails.
In cooking walnut oil is often used as a seasoning; it can add an exquisite taste to your salads and cold sauces. And it is very hard to imagine French and Caucasian cuisine without walnut oil. Nut oil, if overheated, can become bitter.
Oct. 6, 2010 — Regularly eating a handful of walnuts can affect the blood pressure response to stress, according to a new study.
“People who show an exaggerated biological response to stress are at higher risk of heart disease,” study author Sheila G. West, PhD, of Pennsylvania State University, says in a news release. “We wanted to find out if omega 3-fatty acids from plant sources would blunt cardiovascular responses to stress.”

Just like oily fish — salmon, mackerel, and Bluefin tuna — walnuts and some other plant foods contain omega-3 fatty acids, says researcher Sheila G. West, PhD, with Pennsylvania State University, in a news release. Studies have shown that walnuts can indeed improve high cholesterol.
She presented her findings at the American Heart Association’s 5th Annual Conference on Arteriosclerosis, Thrombosis, and Vascular Biology being held this week in San Francisco.
One omega-3 fatty acid — alpha-linolenic acid — has been shown to reduce heart disease, says West. In an earlier study, West found that alpha-linolenic acid can significantly reduce C-reactive protein and LDL “bad” cholesterol, two markers for heart disease.
The walnut contains chemicals called fatty acids, which might be useful as part of a cholesterol-lowering diet. It also contains chemicals that can expand blood vessels, possibly improving circulation and the way the heart works.
